It has often been pointed out that each color has a particular impression and that there are certain similarities and individual differences in the relationships between a color and its impression. We now present a few examples of individual studies that have focused on color impression. In this paper, in order to examine the individual characteristics of color impressions, we propose a method that combines GA, PCA, and CA. GA is used to select suitable parameters from color attributes -namely, RGB, HSI, and L*a*b*. PCA is used to extract characteristics data from the selected parameters. Furthermore, CA is used to classify the data set into groups. In order to demonstrate the effectiveness of this proposed method, computer simulations are performed and the results are analyzed using data gathered from 6 individuals. As a result, characteristics data that were obtained by using GA differed for each subjects. Moreover, classification accuracy, which is the ratio classified same impression data into same groups, was more than 80% for all subjects. It is considered that the proposed method could be one of the effective methods for analyzing individual characteristics of color impression.

In this study, we conducted an experiment that compared 27 schizophrenia patients and 29 healthy subjects in perception of emotions expressed by an NAO humanoid robot. We programmed the robot to express the eight basic emotions proposed by Plutchik (1984) which were anger, anticipation, expectation, joy, trust, fear, surprise, sadness, and disgust using Teshi et al. (2015)’s method of dynamically changing the robot’s eye color. We found a significant difference between the two groups of subjects in their judgements of the robot’s emotions. The results showed that the schizophrenic patients had difficulty in recognizing the robot’s emotions. In addition, the two groups showed different patterns of emotion misperceptions. The schizophrenic group’s misperceptions mistook positive and negative emotions. The misperception of schizophrenic patients may be caused by the similarity of colors and fast blinking cycles. We consider it resulting from the decline in information processing abilities of the schizophrenic patients.

The purpose of the present study was to examine whether art students would evaluate paintings based on the economic dimension of value (EDV). Art students (N = 193) were asked to rate 14 paintings (including seven good arts and seven bad arts selected from the Museum of Bad Art) on four scales of aesthetic evaluation. They were also asked to complete a questionnaire assessing their degree of the EDV. The results demonstrated that the EDV was related to aesthetic evaluations for both good and bad arts. These results suggest that art students with the high EDV appreciate paintings based on the EDV and focus on whether paintings would be sold.

To apply onomatopoeia to product design, we investigated the relationship between the sound symbolism of onomatopoeia and physical quantities. The target of evaluation was the operating tactile sensation of rotary switches. First, a subjective evaluation experiment was conducted in which participants were asked to provide free answers using onomatopoeic expressions related to their impressions of the operating tactile sensation. The obtained onomatopoeia was analyzed by quantitative text analysis using mora as the unit of analysis, and it was found that the phonemes of onomatopoeia used by the participants differed depending on the magnitude of the click torque of switches. Next, we examined the impressions of the onomatopoeia when the click torque of the rotary switch was sequentially changed via 7-point scale evaluation experiments. As a result, the correspondence between tactile sensation and onomatopoeia was grasped quantitatively. This paper shows that onomatopoeia can be used for quantitative product design.

Choreography is one of the important parameters in dance performance. To make dance cool, it is necessary to design the cool choreography. However, beginners can hardly design choreography because they do not know how to judge the choreography good or bad. In this paper, we propose a system which automatically estimates the coolness of choreography for Lock dance and supports for the beginners to design choreography more sophisticated. To realize the proposed system, we focus on the suitability between the dynamics of dance move and music as a parameter of the coolness. We propose the estimation formula of the coolness based on the suitability, and evaluate it experimentally. As the result, it is revealed that the higher the suitability becomes, the higher the coolness becomes especially for the experienced participants feel on the experimented environment. Consequently, it is expected that the proposed system enables beginners to design cool choreography.

Facial expression is one of the most important social skills for smooth communication. Children with autism spectrum disorder (ASD) often have difficulty with facial expression communication and need support to acquire social skills. Therefore, we developed a training system for facial expression and a support system for recognition of facial expressions. In the training system for facial expression, we devised a user interface so that users can enjoy training by themselves. The user can make facial expressions according to the teacher’s image on the PC screen, and check his or her own facial expression and score with the PC camera. In the facial expression recognition support system, the user’s facial expression recognition is supported by displaying the expression of the person in front of the user in words on the smart glasses. These developed systems were evaluated based on usability, and improvements were discussed based on these evaluations.

<p>Currently, robots that are designed to communicate with people, such as service robots, are becoming popular. It is known that expressing emotions can make communication smoothly. Therefore, humanoid robots must have the means to express their emotions. In this study, we focus on the body movements of humanoids and aim to add emotions to them. In this paper, we propose RNNPB-Trans. We conducted experiments to generate movement of the wave and bow with emotion using RNNPB-Trans. The results showed that RNNPB-Trans could generate for waves that express emotion used for training, but could not for bows which is an unknown movement. It seems to be better to extract the features from the movement and then transform the movement features by RNNPB-Trans.</p>

In order to discuss the risk involved in purchasing products that cannot be tried when shopping online, this study investigated the difference in tactual sensations between fabrics and pictures, with a precondition that participants should not touch them. Sixteen participants were presented with 24 different textures (4 cm × 4 cm, 12 fabrics, 12 pictures) and were evaluated for tactual sensation. The result shows that two factors, “material sense” and “touch sense” could be extracted from the tactual sensation values. By interchanging the pictures and fabrics, much of the detailed information of the two factors was lost. The results also showed that fabric colors had psychological effects, which had a high possibility of giving a false impression to consumers. Therefore, if the psychological effect of colors giving a misleading impression is taken into considerations, it can be expected to mitigate the consumers' risk.

While there are reports on the reliability of the universal goniometer (UG) and smartphone application goniometer (SG), there have been no reports on user impressions when using these devices. In this study, impressions of users of UG and SG that are used in clinical practice were clarified and reliability was compared. Questionnaires on user impressions were administered to 13 staff members who work in the clinical field. Measurements in the hip and knee joints of seven participants were taken by three testers, and intraclass correlation coefficients (ICC) were obtained to assess reliability. Results showed that SG was superior in terms of appearance, weight, texture, portability, usability, versatility and readout. SG was inferior in terms of setting up measurement axes. However, SG demonstrated high reliability even when compared to UG. The intra-and inter-rater ICC were 0.51 to 0.89 and 0.65 to 0.75, respectively.

We aimed to reveal typical-color effects to visual search for pictogram. We assumed that the typical colors shorten the response time of the visual search compared to the non-typical colors in the high color-associativity pictograms. In order to verify this hypothesis, we investigated typical colors and color- associativity of each pictogram in the first experiment and measured the response time of the visual search tasks. We analyzed the data through the color- associativity and the complexity of components perspective. As a result, we obtained the two conclusions as follow; 1) typical colors do not always affect response times, 2) response time is shortened in the typical colors pictograms that have the high color-associativity and consist of only one component. These results contribute to proposing the color design which permits efficiency in searching for pictograms in the facilities.

The purpose of this paper is to consider the Kansei (sensibility) of the architect Le Corbusier (1887-1965), concerning the process of change of the architectural concept on ‘Window’ from the viewpoint of Kansei-philosophy. Through the analysis of the architectural works, the author pointed out to Le Corbusier's 9 types of windows, ‘fenêtre en longueur (strip window)’, ‘pan de verre (glass wall)’, ‘pan de verre irrégulière (irregular glass wall)’, ‘pan de verre ondulatoire (wave glass wall)’, ‘aérateur (ventilator)’, ‘fenêtre (conventional window)’, ‘briques de verre (glass block)’, ‘claustras’ and ‘canon (gun)’. Through the analysis of the design process, the author concluded that Le Corbusier purified the physiological and multiple functions of the window by adapting each type of window.

“Resolution” in music theory means the chord progression by the transition from dissonance to consonance for providing more profound satisfaction to listeners than consonant chord only. The authors have investigated similar effects in temporal color transitions as an analogy of musical perception’s effect. In Part (1), the authors used various display patterns of three-colors combinations, measured the score of the color consonance with a sensory test, and revealed conditions where the “resolution” effect is enhanced. In Part (2), the authors focus on the conditions of gaze control. The fixation point appears as a small white dot on the black screen, and the observers are advised to fix their gaze onto the point. The white dot continues to appear while the observers watch the color arrangements and the transition. The experimental results suggest that the “resolution” effect appears more clearly when the color arrangements are captured in peripheral visual fields.

Our goal is to promote brain health through “bSports” (brain-Sports), a form of social sport competition using brain-machine interfaces. As the core technology, we have been developing an electroencephalography-based cognitive training system, “Neurotrainer,” using event-related potential as a virtual “mind switch” to control games. Here, we aimed to assess the performance of the Neurotrainer under competitive conditions between players. Fifteen pairs of healthy adults, including older people with tendency of degrading motor functions, were involved in a one-hour session of 4 games. Each player activated the mind switch to select one of eight pictograms to control his/her robot avatar for its desired action. All players regardless of age performed well at the level of about 85% success rate and reported that they had fun with our body-free technologies. These results suggest that bSports is an effective cognitive training and social activity that can be appreciated by people across all generations.

In this paper, the classification model of subjective affective value, its measurement, and the quantitative-analysis method were proposed first. Next, based on the proposal method, the value measurement experiment including the intuitive and unconscious decision-making phenomenon of the real world was conducted, and also separation and extraction of the affective value, and presumption of the value structure which became a decision-making standard by the analysis and evaluation of the degree of incidence especially were tried. As mentioned above, the validity of the proposal method was examined. As a result, it came to prove the validity of the proposal method.

Nagoya Cochin is one of Japan’s famous chicken breeds and was also the first domestic commercial chicken. The eggshell is a pink cherry-blossom color, with white speckles on its surface. The purpose of this study is to develop an eggshell color index for quality control to improve the commercial value. This study consists of two experiments. In the first experiment, the eggshell color of sixty eggs was measured by a colorimeter TC-8600A, and a visual evaluation using photo images of each egg was conducted by fourteen visual inspection experts. They scored on a Likert scale of five steps on four criteria: attractiveness of color, attractiveness of white speckles distribution, overall attractiveness, and preference. The relationship between the eggshell color and the visual impression was analyzed on a Hunter Lab color space. In the second experiment, a range of color variations of eggshells were generated on a screen using Adobe Photoshop, and a visual evaluation of three hundred and fifteen egg images was conducted by seven experts. It is hoped the results from both experiments will be useful for agricultural producers to develop more attractive products and increase the commercial value of Nagoya Cochin chickens.

Kawaii is one of the representative concepts of Japan-original Kansei. In this paper, we categorized Kawaii motion of Roomba and investigated the correlation between physical properties of motions and Kawaii-ness. First, we classified motions of Roomba into 10 types. Impressions of those motions were investigated and three of them were found to be Kawaii by subjects. Based on the findings, we formed a hypothesis that variations in acceleration, namely the jerk, affect Kawaii-ness. Second, we evaluated parameters of seven physical properties (position, velocity, acceleration, angle, angular velocity, angular acceleration, and time) of three Kawaii motions of Roomba. Then, we created 24 types of robot motions and evaluated impressions of them. The physical features of created motions were correlated with the Kawaii-ness of them. The result indicated that the jerk certainly affects the Kawaii-ness of motion but not always. It clearly indicated that the Kawaii-ness of motion is multifaceted.

The idea of ecosystem services has been highlighted in order to identify a variety of benefits that human beings obtain from other life forms and to raise people's interest in conserving biodiversity. This idea helps us recognize the connection between our lives and environments and more actively participate in ecological activities. While this sort of instrumental approach to the conservation of biodiversity is particularly important for the growth of public participation, it also limits our understanding of its purposes. This paper, on the basis of field research conducted in Sado, Niigata, illustrates complex value issues involved in conserving biodiversity and discusses the importance of our kansei to uncover various values of the surroundings. As an approach for enhancing such kansei, the authors argue that multi-generational dialogue contributes to sharing different views of the participants and thereby cultivating a comprehensive perspective in environmental decision-processes.

This paper discusses the changes of magazines which women read according to the age using figures of the network, which we got from the answers to questionnaire of women's junior college students. The link of the network expresses frequent combinations of magazines read in the same period or frequent changes of magazines which women read. This paper covers fashion magazines, comic magazines and animation magazines. At first, it is found that the combination of magazines with a similar property are read in the same period. Next, changes of magazines which women read is clarified. 51.22%, 28.66%, and 19.51% of the college students read “Chao,” “Ribon,” and “Nakayoshi” in their childhood, respectively. Readers of “Chao” and those of “Ribbon” come to read fashion magazines or boys' comics for teenagers, and then street fashion or girly fashion magazines. “Nakayoshi” readers, however, tend to continue reading comic magazines sequentially.
